My digital OPK is giving suspicious results. Yesterday (CD13) my temp plummeted and my digital said peak (solid smiley--never got any flashing smileys) (and I got a positive cheapie yesterday, as well). This morning, however, my temp went back up high, and I tested with my other digital and it said negative. However, the insert suggests otherwise. The lines look positive. Photos below. I usually get my + OPK CD14 (today), but I'm not sure what's going on with my temperature and OPKs. Charts below. Insight, anyone?
